I recently purchased a nice running 1947 Dodge COE with a 6 cyl engine and single speed rear end. I am trying to determine what designation was given to this old truck. Also does anyone know of a good source of parts, books on coe's etc. I need the air cleaner assembly. I have already been to Amazon.com for the books. If it is easier to reply by phone my number is 805 710-3617 Best Regards to all and thanks for your help!!! Jim
